The hydrogen bomb


The Hydrogen bomb was foremost suggested by Edward Teller in 1942 but active work on it was pursued in the summer of 1942 by Oppenheimer, Teller, Los Alamos and others. The first thermonuclear bomb was exploded in 1952 atEnewetak by the United States, the second in 1953 by Russia ( so the USSR ) . Great Britain, France, and China have besides exploded thermonuclear bombs, and these five states comprise the alleged atomic club—nations that have the capableness to bring forth atomic arms and admit to keeping an stock list of them. Several other states either have tested thermonuclear devices or claim to hold the capableness to bring forth them, but officially province that they do non keep a reserve of such arms ; among these are India, Israel, and Pakistan. South Africa ‘s apartheid government built six atomic bombs but dismantled them subsequently.

What is Hydrogen Bomb?

Hydrogen bomb is based on atomic merger reaction and it deducing a big part of its energy from the atomic merger of hydrogenisotopes. The H bomb maps by the merger, or fall ining together, of lighter elements into heavier elements.The H bomb is besides known as a thermonuclear bomb because highly high temperatures are required in order to originate merger reactions.

Hydrogen bomb is based on procedure called “Nuclear fusion” . Nuclear merger is the procedure by which atomic karyon articulation together to organize a heavier karyon. The merger of two karyons with lower mass thaniron by and large releases energy while the merger of karyon heavier than Fe absorbs energy. In the simplest instance of H merger, two protons have to be brought near plenty for their common electric repulsive force to be overcome by thenuclear forceand the subsequent release of energy.


Energy release Q=17.6 MeV

Design of H bomb

All thermonuclear arms bing in the universe today appear to be based on a strategy normally called the “ Teller-Ulam design” . It contain the Staged detonation of fission ( primary ) bomb and merger ( secondary bomb ) . The merger bomb is triggered by rapid daze driven compaction ( Ulam ) which is enhanced by radiation force per unit area ( Teller ) from released X ray and ?-ray flux.

Primary fision device contain: –

nucleus: U239 and U235 plus H2+H3 Booster

shell: U238 Tamper

High explosive lenses

Secondary merger device contain: –

Radiation Channel

U239 PU flicker stopper

Li6, H2, H3 merger cell

U238 Tamper

Design of modern Hydrogen-bomb Hydrogen bomb design is based on a bomb casing incorporating implosion fission bomb and a cylinder shell of U238 tamping bar ) . Within the tamping bar is the Li6 Deuteride merger fuel and ahollow rod of Pu239 in the Centre of the cylinder. Separating the cylinder from the implosion bomb is a shield of U238 and plastic froth that fills the staying infinite in the bomb casing The explosion of the trigger bomb will do the undermentioned sequence of events:

  1. The fission bomb implodes, breathing X raies.
  2. X-rays heat the inside of the bomb and the tamping bar prevents premature explosion of the fuel.
  3. The heat causes the tamping bar to spread out and fire off, exercising force per unit area inward against the Li deuterate. The Li deuterate is squeezed by about 30-fold.
  4. The compaction daze moving ridges initiates fission in the Pu rod.
  5. The fission rod gives off radiation, heat and neutrons.
  6. The neutrons enter the Li deuterate and generate tritium.
  7. The combination of high temperature and force per unit area is sufficient for tritium-deuterium and deuterium-deuterium merger reactions to happen, bring forthing more heat, radiation and neutrons.
  8. The neutrons from the merger reactions induced fission in the uranium 238 pieces from the tamping bar and shield.
  9. Fission of the tamping bar and shield pieces produced even more radiation and heat.
  10. The bomb explodes.


Hydrogen bombs are used as arms in many states. Apart from their usage as arms, atomic explosiveshave been besides tested and used for variousnon-military utilizations. When long term wellness and clean-up costs were included, there was no economic advantage over conventional explosives. Man-made elements such aseinsteiniumandfermium, created by neutron barrage of U and Pu during thermonuclear detonations, were discovered in the first thermonuclear bomb trial. In 2008 the world-wide presence of new isotopes from atmospheric proving beginning in the 1950s was developed into a dependable manner of observing art counterfeits, as all pictures created after that period contain hints ofcesium-137andstrontium-90, isotopes that did non be in nature before 1945. An of import facet of merger energy in contrast to many other energy beginnings is that the cost of production isinelastic. The cost of air current energy, for illustration, goes up as the optimum locations are developed foremost, while farther generators must be sited in less ideal conditions. With merger energy, the production cost will non increase much, even if big Numberss of workss are built. It has been suggested that even 100 times the current energy ingestion of the universe is possible.Some jobs which are expected to be an issue in this century such asfresh H2O shortagescan really be regarded simply as jobs of energy supply. For illustration, in desalinationplants, seawatercan be purified throughdistillationorreverse osmosis. However, these procedures are energy intensive. Even if the first merger workss are non competitory with alternate beginnings, merger could still go competitory if big graduated table desalinization requires more power than the options are able to provide.Despite being technicallynon-renewable, merger power has many of the benefits of long-run renewable energy beginnings every bit good as some of the benefits of the much more limited energy beginnings as hydrocarbons and atomic fission. Like these presently dominant energy beginnings, merger could supply really high power-generation denseness and uninterrupted power bringing.


In 1945 an atomic bomb was dropped on Hiroshima, it killed at least 70,000 Nipponese and many were injured. It is assumed that the H bomb is 1000 times more powerful than an atomic bomb. [ 5 ] So if we use fusion power as beginning of energy instead than arms so it should be more good for us. Fusion power would supply much more energy for a given weight of fuel than any engineering presently in usage, and the fuel itself ( primarilydeuterium ) exists copiously in the Earth ‘s ocean: approximately 1 in 6500 H atoms in saltwater is deuterium.Although this may look a low proportion ( about 0.015 % ) , because atomic merger reactions are so much more energetic than chemical burning and saltwater is easier to entree and more plentiful than fossil fuels, some experts estimate that merger could provide the universe ‘s energy demands for 1000000s of old ages. Therefore Hydrogen bomb has both advantages and disadvantages but if we use fusion power as energy beginning so it should be more good for all of us.
